好的,我用该代码解决了这个问题:
在我的登录活动(第一个活动)中,我需要传递用户名和密码字符串:
btnLogin.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
String userName = txtUsername.getText().toString();
String password = txtPass.getText().toString();
//instance for UserFunctions.
UserFunctions userFunction = new UserFunctions();
JSONObject json = userFunction.loginUser(userName, password);
//Check login response
try {
if(json.getString(KEY_REQUESTRESULT)!= null ){
txtErrorM.setText("");
//Log.e("Passed fine:", "first if condition");
String res = json.getString(KEY_REQUESTRESULT);//Obtaining the value 0 or 1 from the KEY loginstatus from JSONObject.
if(Integer.parseInt(res) == 1){
Intent iii = new Intent("com.mariposatraining.courses.MariposaTrainingActivity");
Bundle bundle1 = new Bundle();
Bundle bundle2 = new Bundle();
bundle1.putString("UN", userName);
bundle2.putString("PW", password);
iii.putExtras(bundle1);
iii.putExtras(bundle2);
//iii.putExtra("userName", userName);
//iii.putExtra("Password", password);
startActivity(iii);
finish();
//Log.e("OBJECTOO", json.toString());
}
我将此字符串发送到 TAB HANDLER CLASS,然后发送到管理此信息的活动:
public class MariposaTrainingActivity extends TabActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
TabHost tabHost = getTabHost();
TabHost.TabSpec spec ; //recurse to the property tabs
Intent intent; //intent for open tabs
//created intent for open the class tab1
intent = new Intent().setClass(this, ListViewerIncompleted.class); //List 2 Incompleted
spec = tabHost.newTabSpec("ListViewerIncompleted").setIndicator("INCOMPLETED").setContent(intent);
tabHost.addTab(spec);
Bundle bundle1 = getIntent().getExtras();
String userName=bundle1.getString("UN");
Bundle bundle2 = getIntent().getExtras();
String password=bundle2.getString("PW");
Bundle bundle3 = new Bundle();
Bundle bundle4 = new Bundle();
bundle3.putString("UN", userName);
bundle4.putString("PW", password);
intent.putExtras(bundle3);
intent.putExtras(bundle4);}}
在类中使用此信息:
Bundle bundle3 = getIntent().getExtras();
String userName=bundle3.getString("UN"); //Getting the userName
Bundle bundle4 = getIntent().getExtras();
String password=bundle4.getString("PW");
希望这能给你一些想法......
